BRUSH AND MODE OF MAKING THE SAME.

SPECIFICATION forming part of Letters Patent No. 449,061, dated March24, 1891.

Application filed July 3,1890.

T0 aZZ whom it may concern.-

Be it known that I, ARTHUR H. WOLCOTT, a citizen of the United States,and a resident of WVinthrop, in the county of Suffolk and State ofMassachusetts, have invented new and useful Improvements in Brushes andMode of Making the Same, of which the following, taken in connectionwith the accompanying drawings, is a specification.

This invention relates to improvements in brushes and mode of making thesame, and it is carried out as follows, reference being had to theaccompanying drawings, wherein Figure 1 represents a centrallongitudinal section of the improved brush. Fig. 2 represets a bottomview of the improved head and ferrule. Fig. 3 represents a bottom viewof the bristle-expander, and Fig. 4 represents a bottom view of amodification of said ferrule and its bristle-expander.

Similar letters refer to similar parts wher ever they occur on thedifferent parts of the drawings.

The improved brush consists of the following parts, namely: a metal headA, having a entral perforation for receiving the handle B. In one piecewith the metal headis made the bristle-inclosing ferrule A, asvshown inFigs. 1, 2, and at. In practice I make in one piece with the head A acentral hollow and tapering bristle-expander A, the interior of which isadapted to receive and hold the handle B, as shown in Fig. 1.

On the interior of the ferrule A, I make a shoulder a, on which is madeto rest the metal plate 0, having a central perforation for receivingthe central bristle-expander A and in one piece with said metal plate 0'are made a series of longitudinal bristle-expanders C 0, each of whichis preferably made slightly tapering from its base to its point, so asto permit their being easily driven in and between the mass of thebristles D, as shown in Fig. 1.

The invention is equally useful for round, oval, or flat brushes. InFig. 4 I have represented a flat-brush ferrule 00, with an elongatedcentral expander a made according to my invention, and in said figure Ihave represented modified forms of bristle-expanders 0 extending fromthe plate 0 The ex- Sarial No. 357,627. (Model) panders may be made ofany suitable form or cross-section-such as, for instance, circular,square, rectangular, polygonal, or other forms grouped together withsuitable spaces between them, as may be found most practical anddesirable, or they may be arranged in the form of annular rings, withoutdeparting from the spirit of my invention.

Back of the plate O is left a hollow chamber a, as shown in Fig. 1,which adds to the length of the ferrule and serves to give a longerbearing to the handle end when driven into the socketed central expanderA, or directly in and between the central portion of the bristles, asshown.

In making the brush I proceed as follows: The handle B is preferablyfirst driven into the socketed part A, and the plate 0 is driven intothe ferrule A and against the shoulder a, after which the bristles D arefirmly secured between clamps, as is common in the art of makingbrushes, and a suitable gum or adhesive substance applied to the upperends of the said bristles, after which the ferrule A is placed above thebristles and driven around the same, causing the central expander A orhandle end, as well as the expanders O O, to be driven into and betweenthe mass of the bristles, as shown in Fig. 1, by which the bristles aremost firmly secured to the ferrule and the bristle-expanders.

Having thus fully described the nature, construction, and operation. ofmy invention, I wish to secure by Letters Patent and claim- 1.
